| 英文摘要 | Corrosion inhibition of iron in H2SO4 by polyacrylic acid (PM) was investigated using electrochemical techniques at 30 degrees C. Results obtained indicate that PAA inhibited the corrosion of iron in the acid medium. Inhibition efficiency increases with increase in PAA concentration and synergistically enhanced on addition of iodide ions. Potentiodynamic polarization results suggest that PM functions as a modest cathodic inhibitor. The adsorption of PAA onto the iron surface followed Temkin adsorption isotherm. FTIR analysis revealed that the synergistic effect due to co-adsorption of iodide ions and PM is co-operative in nature. (C) 2010 Published by Elsevier Ltd. |
